The
levels of pollution in the air is increasing by the day. As the emissions
from vehicles and industries reach an all time high, there isn't much hope
for things to be changing for the better in the recent future. This problem
has been further compounded by air tight buildings we live in. built to
conserve energy, these places do not allow air to either leave or come
inside. The result is that the impurities already present in the air has no
way to get out. And since no oxygen can flow in from the outside, the
possibility of oxygen cleaning the air is also nullified. |
The only solution to this problem would be
air purifiers. Impurities in the air
have been linked to several respiration illnesses including asthma. It has also
been held responsible for problems like sinusitis. Studies show, that breathing
impure air can also severely affect the quality of our sleep. What all these
mean is that having an air purifier at your place becomes imperative at the
present situation.
There are a whole
variety of air purifiers available in the market. As the
industry grows bigger - sales having crossed $100 million - the number of models
on offer keeps growing. Apart from the capacity and looks, air purifiers can be
differentiated on the basis of the kind of filters it uses.
One of the most common air purifiers are the ionic air purifiers. Ionic air
purifiers actually have ionizers inside them. Basically such purifiers work on
the principle of static electricity. When switched on, the plates inside the
purifier gets electrically charged which subsequently charge the dust and smoke
particles. Once they are charged, they will cling on to the neutrally or
positively charged surface of the air purifier.
However there is one drawback with ionic air purifiers. The heavier particles
may actually fall off if two dissimilarly charged small particles clump
together.
The ionic air purifiers however come with a pre-filter which actually separate
the larger dust particles from the smaller ones. So in a way the problem of
larger particles falling off is taken care of.
Recently better air purifiers with more advanced filters have been launched. HEPA filters can purify air to the extent of 99.7 percent. Such figures are
truly amazing when compared with ionic air filters. However, if someone in your
family doesn't suffer from severe respiration problems, you can well do with an
ionic air filter.
